IMPORTANT....
electrons are revolving around nucleus for the stability of atom thats what was postulated by bohr.but many students ask "WHO TOLD THE ELECTRONS TO REVOLVE AROUND THE NUCLEUS...?THEY CAN'T GET THE POINT THAT COULOMB FORCE BETWEEN ELECTRONS AND NUCLEUS PROVIDE THE REQUIRED CENTRIPETAL FORCE FOR THE STABILITY.BUT MAIN QUESTION IS WHY OR WHO TOLD THEM TO DO SO..?

IT'S IMPORTANT GUYS...SOME1 PLEASE ANSWER....

anonymous · Answer

electrons don't really revolve around nucleus they just move here and there like mad particles in a specific space around nucleus making an electron cloud that is called orbital of electron. . .

anonymous · Answer

Since the electrons are moving, but also attracted to the nucleus, they will orbit it.  All "orbiting" means is that you're moving and you can't escape to infinitely far away.  This is the natural state of two objects that are in relative motion and attracted to each other.  Any *other* situation would be highly unnatural and require some explanation.

anonymous · Answer

@theyatin,  that is not correct.  You are mistaking an orbital -- a mathematical description of the outcome of measurements -- for an actual description of electronic motion.  It is not.

thanks carl....
but then how can we account for the spinning of the electron around its own axis...

anonymous · Answer

You don't, because it's not.  So far as we know, the electron is a point particle -- it has a radius of zero -- and such an object cannot spin on its own axis.

Electron "spin" is a relativistic effect that has nothing to do with any spinning.  It's just called spin because the physics happen to be very similar to what they would be IF it were, in fact, spinning, namely it's a vector object, it obeys the rules of addition of angular momentum, interacts with a magnetic field the same way, et cetera.  But there are significant differences, e.g. half-integer values of angular momentum are allowed (which makes no sense if it was a REAL spinning object).
